FAUCET 0R BATH COCK.

Application led September 15, 1919. .Serial No. 323,881.

To all whom 'it may conce/in.'

Be it known that LEON B. Ynlsi-za, citizen of the United States. residing at Cleveland, in the countyof Cuyahoga and State of Ohio, has invented certain new and useful lmprovements in Faucets or Bath Cocks, of which the following is a specification.

This invention consists in an improvement in valves, and more particularly in faucets, bibbs or cocks'. and the object of the invention is to provide a valve body with a re* movable tapered plug. which is ground with,- in upper and lower correspondiugly-tapered seats within the body. This tapered plug is also provided with an inlet opening surrounded by a valve seat and particularly constructed internally to removably hold a valve member in operating relation opposite said inlet opening and seat. A screw collar is used to press and hold the plug to its ground seat within the body, and a check valve is also confined within the body by the tapered plug where it is adapted to be held open bythe movable val-ve member at all times except when such valve member is bodily removed from the plug. its function being to automatically stop the outflow of water whenever the valve member is removed for inspection and repairs.

In the accompanying d1'awing,.Fig. 1 is a side view` and Fig. 2 a vertical sectional viewof a faucet or bath cock .embodying my improvements. Figji is a side view of the vscrew sleeve and movable Ivalve member as it appears when removed fromthe tapered plug. Fig. 4is a side elevation of the screw collar. and Fig. 5 is a similar view ofthe tapered plug, Eig. 6 shows the check valve alone. and Fig. 7 is `a side View of the valve body alone. Fig. 8 is a plan view of the washer used to fasten the valve body to the base slab, and Fig. 9 is a sectional view of a modified form of tapered plug and valve member which may be placed Within the valve body as asubstitute for the plug and valve member shown in the other figures.

The invention comprises a cylindrical cast metal body 2 having a base flange 3 anda short round extension 4 with internal screwthreads adapted to provide direct coupling connection, with a threaded water supply pipe 5. A nut 6 on the pipe. and the eXtension 4 are of the same diameter so that the valve body. nut and pipe may be introduced together through the opening 7 in the slab 8, and a separate washer 9 with an opening tween the bottom side of the slab and nut.y

,6 to permit the body to be clamped in place upon the slab.. either by turning the nut or the -valvebody. This permits quick assembly of the valve body to the slab, and also a simple and inexpensive construction of valve as a whole.

Body 2 is a plain cylinder having a short straight spout 11 'at one side with a drip chamber or recess 12 at its inner end, and the, neck of the body is screw-threaded to permit the attachment of a screw-collar 14 wherewith a tapered removable plug 15 may be pressed downwardly in tight-fitting relation within thev body. which is formed with a' flaring chamber or tapered -bore 16 extending' downwardly onstraight lines from the upper edge of the neck to an annular shoulder 17 where a reduced intake passage 18 is provided in extension 4. An annular channel 19 internally of the body subdivides and intersects the tapered bore approximately midway ofits length opposite spout 4 into two separated tapered seats having exactly the same taper to permit the plug to be ground uniformly thereto. In other words. the round tapered plug 15 has the same tapering formation as bore 16 above and below the water-distributing channel 19, and an exceedingly effective leak-proof joint is provided by grinding the plug its full length within both seats in the body and employing the lscrew-'collar 14 to press and hold the plug to said tapered seats. Screw collar 14 is sleeved over the reduced upper end of the plug and bears down upon an end shoulder 20 on the plug when screwed down upon the neck thereon, and this collar also acts'to lift and withdraw the plug from its seat when unscrewed from the neck; especially when the overhanging head or flange 21 of a removable sleeve or thimble 22 is `in place within the plug as shown in Figa 1.

Sleeve 22 is screwed within the upper end of plug -15 and is provided either with ya fquick screw thread internally as seen in Fig. 1. or with a plain opening of differential diameter lcentrally therethrough as seen in F ig. 9. The construction shown in Fig. 1 is designed to permit the'closing of the water passage 23 inthe end of the plug by al compression valve 24 having a screwthreaded` stem 25 extending upwardly through the 'plug and sleeve, andthe water from passage 23 escapes to spout 11 through of the screw thread on the stem within the screw sleeve 22, and this limited movement is taken advantage of in regulating the movement of a check valve 29 confinedwithin `the lower end of the tapered bore beneath plug 15. This check valve has a Haring valve head adapted to seat within the flaring end ofthe plug to close the entrance to passage 23 whenever the main valve 24 is removed from the plug for inspection and repairs. That is, the water pressure seats said check valve under those conditions, but not otherwise because the ribbed guiding stem 30 of the check valve is made long enough to engage the washer holding screw 31 at the end of main valve 24 and thereby hold the check valve open when the main valve 24 is raised to its limit under ordinary usage.A In briefthe check valve cannot close when the main valve is wide open, but is adapted to close-paage 'regulate'the tension of the spring and thev extent of movement ,of valve 32 relatively v to the seat at the lower end of the plug.

Body 2 will seat and hold either the valve.

plug 33 or the plug 15, thereby permitting substitution of one for the other prior to or subsequent 'to lthe installation offbody 2 in a llavatory or other lace of use.' Thus, when either `plug is `1n place the tapered ground joint between the plug and body provides an absolutely' water-tight .union i without the aid of packing or any other medium other than screw collar 14, and the joint is not a'ected by extreme changes in temperature inside or outsideof the body. It will'be observed that the plug hasno means of its own for dislodging-it 'from its ground in joint, and my experience is that it 1s practically impossible to move it from 1ts seat without s pecial means for this purpose. Such means are provided in thiS.in-

The opening.

tion' with said water passages in said body, a screw collar adapted Ato hold said plug stance by the screw collar 14: and the iange 21 of sleeve 22, which extends outward over said collar suiiijciently to be engaged by said collar when the colla-r` is unscrewed or raised by turning to the leftl and which forcibly raises the plug because the sleeve 22 is screwedinto the plug.

What I claim is: y

1. In a faucet or cock, a body having intake' and outlet water passages and atapered bore communicating with said passages, a tapered plug ground within said tapered bore having a central water passage, a screw collar adapted to secure said plug 'removably within said body, a valve member adapted to control the flow of water through' the passage in said plug, a sleeve 4removably screwed within the outer end'of said plug and having a iange overlying said collar and adapted to support and hold said valve in operatingposition therein, and means wherewith to operate said valve member.

2.'In a faucet orl cock, a body having water passagesV and a tapered bore longitudinally therein, a .tapered plug ground within said tapered bore having an end inta'lre and side openings centrally between its 'ends adapted to have open communicawithin` said; body, a screw-threaded sleeve removably mounted within'the outer end of said plug, a valve member within said plug adapted to control the fiow of water through its intake and side openings, and, said valve member having a screw-threaded stem in screw-engagement with said sleeve 'and providedwith an operating'handle at its outer end. 'n l 3. In a faucet or cock, a body having a spoutv and a tapered bore longitudinally therein opposite said spout and provided with a' screw-threaded extension with a reduced water passage therein opposite the 105 smaller end of said tapered bore, a tapered plug ground within said taperedbore having a central 'end passage and an internal chamber with a valve .seat .and side openings, a valve member within said 'plug 130 adapted to engage the valve seat therein, a screw sleeve removably mounted within the outer end of said plug, a screwfthreaded valve stem for said valve member in screwengagement with said sleeve, a handle for 1115 sald valve stem, and means adapted to seeure said plug tightly and removably with in said body.
